In a medium bowl, combine the rolled oats, peanut butter, honey, and vanilla extract. Stir until well combined.
Stir in the mini chocolate chips (if using), chopped nuts, dried cranberries, and chia seeds. Mix until everything is evenly distributed.
Roll the mixture into balls, about 1 inch in diameter. If the mixture is too sticky, you can chill it in the refrigerator for about 15-20 minutes before rolling.
Place the energy bites on a baking sheet lined with parchment paper and refrigerate for at least 30 minutes to firm up.
Store the energy bites in an airtight container in the refrigerator.
Notes
These energy bites are best stored in the refrigerator and will keep for up to a week. They make a great pre-workout snack or a healthy treat to curb your sweet cravings.
